WASHINGTON - NASA EDGE, an award-winning talk show known for offbeat, funny and informative behind-the-scene stories about the space agency, will celebrate Sun-Earth Day 2010, with a live webcast about our sun and its effects on Earth. The program will air at 1 p.m. EDT, Saturday, March 20, from the exhibit floor of the National Science Teachers Association conference in Philadelphia.

This year's focus is magnetic storms created by the sun. Magnetism, a force that affects our everyday lives, plays a key role in the workings of the sun. Its force also is responsible for coronal mass ejections, the most violent explosions in the solar system.

NASA research about these storms will help scientists increase their understanding of the connections between the sun and its planets. Scientists also will be able to better predict the impact of solar activity on humans and technological systems.

The NASA EDGE program will feature interviews with scientists, educators and students. Viewers will hear discussions and see demonstrations about the power of magnetism and how magnetic storms affect them. Science centers and museums around the world will provide images from NASA satellites studying the sun and other multimedia products for educators, students and the public.
